VHE Gamma-ray Observation of Crab Nebula with HAGAR Telescope Array
B. B. Singh, R. J. Britto, V. R. Chitnis +13
HAGAR is a system of seven Non-imaging Atmospheric Cherenkov Telescopes located at Hanle in the Ladakh region of the Indian Himalayas at an altitude of 4270 meters {\it amsl}. Sinc…
Optical and NIR observations of the nearby type Ia supernova SN 2014J
Shubham Srivastav, J. P. Ninan, Brajesh Kumar +4
Optical and NIR observations of the type Ia supernova SN 2014J in M82 are presented. The observed light curves are found to be similar to normal SNe Ia, with a decline rate paramet…
Insights into the evolution of symbiotic recurrent novae from radio synchrotron emission: V745 Scorpii and RS Ophiuchi
N. G. Kantharia, Prasun Dutta, Nirupam Roy +6
We present observations at 610 MHz and 235 MHz using the Giant Metrewave Radio Telescope (GMRT) of the recurrent nova V745 Scorpii which recorded its last outburst on 6 February 20…
Multi-frequency, Multi-Epoch Study of Mrk 501: Hints for a two-component nature of the emission
A. Shukla, V. R. Chitnis, B. B. Singh +8
Since the detection of very high energy (VHE) -rays from Mrk 501, its broad band emission of radiation was mostly and quite effectively modeled using one zone emission scenario.…
An HI shell-like structure associated with nova V458 Vulpeculae?
Nirupam Roy, N. G. Kantharia, S. P. S. Eyres +4
We report the radio detection of a shell-like HI structure in proximity to, and probably associated with, the nova V458 Vul. High spectral resolution observation with the Giant Met…
Multiwavelength study of TeV Blazar Mrk421 during giant flare
A. Shukla, V. R. Chitnis, P. R. Vishwanath +7
Context: The nearby (z=0.031) TeV blazar Mrk421 was reported to be in a high state of flux activity since November, 2009. Aims: To investigate possible changes in the physical para…
